[en] Evidence is presented for the desirability and cost-effectiveness of acquiring computerized tomography (CT) facilities for selected VA tertiary care facilities. The rationale is that hospitals offering comprehensive multidisciplinary therapeutic services must also possess equally comprehensive diagnostic capabilities. The current status and clinical applications of CT are discussed, together with cost analysis, workload data, and relative costs of CT exams at participating VA hospitals having in-house capabilities. Criteria are presented for the acquisition and assignment of CT units, and costs are given for CT scans on a contract basis
